Koby Nelson

Come work with me in a vibey old factory-turned-recording-studio and let’s make your best sounding songs yet.  I’m a recording and mixing engineer based out of central CT specializing in rock and pop music.

I built an invaluable foundation of skills while working at the renowned House Of Loud recording studio as an engineer for producer David Bendeth. There, I worked with bands such as Beartooth, Of Mice & Men, We Came As Romans, Tonight Alive, Fire From The Gods, and many more. Today, I’m putting that experience to use as a stand-alone engineer/producer and helping more bands reach that high level.
